Useful aliases for Python and pew and conda

python_aliases.sh

## General stuff
## Uncomment if pip cache takes up too much space
# alias pip="python -m pip --no-cache-dir" 
## or even better simply symlink ~/.cache/pip

alias spyder='env python /usr/bin/spyder'
alias spyder3='env python3 /usr/bin/spyder3'
alias jupyter-clean-checkpoints='find -name ".ipynb_checkpoints" -type d | xargs rm -rf'
alias ipcluster-mpi='ipcluster start -n 2 --engines=MPIEngineSetLauncher'

## Install / Uninstall your virtualenvs to appear as kernels, allowing you to launch them from a 
## system-wide or user-wide Jupyter Lab / Notebook installation
## Similar functionality is offered by https://github.com/Anaconda-Platform/nb_conda_kernels
alias ipykernel-install='ipython kernel install --user --name=py-$(basename $VIRTUAL_ENV)'
alias ipykernel-uninstall='jupyter kernelspec uninstall py-$(basename $VIRTUAL_ENV)'
alias ipykernel-list='jupyter kernelspec list | grep "\/py.*"'

## Pew aliases to behave like virtualenvwrapper
alias workon='pew workon'
alias deactivate='exit'
alias mkvirtualenv='pew new'
alias lsvirtualenv='pew ls'
alias rmvirtualenv='pew rm'
alias cpvirtualenv='pew cp'
alias cdproject='cd $(cat $VIRTUAL_ENV/.project)'
alias cdsitepackages='cd $(pew sitepackages_dir)'
alias cdvirtualenv='cd $(pew dir)'

## Conda aliases to behave like virtualenvwrapper
# alias workon='conda activate'
# alias deactivate='conda deactivate'
# alias mkvirtualenv='conda create'
# alias lsvirtualenv='conda-env list'
# alias rmvirtualenv='conda-env remove'
# function cpvirtualenv{
#   conda create --clone $1 --name $2
# }
